Capture file appears to be damaged or corrupt

I installed yesterday wireshark 2.2.6 on Ubuntu and tried to use the Developers Option on my phone to capture the btsnoop log file related to the blueetoth traffic (I'm trying to track down packets from my phone to a ble device).
Just to explain every detail: I found the log on my phone and sent it to my laptot with Telegram in order to read it.
I had no problems for the first tries, then today I did the same exact steps but the dimension of the file became a lot bigger (from 500B to 63KB) and when I try to open it with wireshark I get the message: "The capture file appears to be damaged or corrupt. (btsnoop: File has 1869574144-byte packet, bigger than maximum of 262144)"

I'm not sure how to solve this as it seems the problem lies in the dimension of the packets, but I don't know how to solve it.
Thanks in advance for your assistance.
